Controller overriding in ZF2

Question

I'm new to Zend Framework 2. I'm starting a project and I want its security being managed by ZfcAdmin, ZfcUser, ZfcUserAdmin and BjyAuthorize. The first thing I'm trying to do is modify the creation users' process. I want to be able to assign roles to a new user right after its creation. The first problem I'm facing is when a user is created, the controller redirects me to the users' list page. I need to change this behaviour, I want to be redirected to the edit page, where I'll be able to choose N roles for the recently created user (that'll another war with entities...). I've chosen to override the UserAdminController (ZfcUserAdmin). That's what I've done to achieve that: 1. I load my administration module (MyAdministration) in the last place in application.config.php, in order to be able to override other modules' properties. 2. I override ZfcUserAdmin controller in MyAdministration/config/module.config.php in order to use mine: ``` (...) 'controllers' => array( 'invokables' => arr…

Accepted Answer

You are correct the template name can be injected by a listener. That is under this single one condition: if there is no template name set.

So for this action the inject template listener injects the template name:

```
namespace MyModule;

class MyController
{
  public function myAction()
  {
    return new ViewModel;
  }
}
```

The template will be `my-module/my-controller/my-action`. However, if you set the template, the listener will be skipped:

```
namespace MyModule;

class MyController
{
  public function myAction()
  {
    $view = new ViewModel;
    $view->setTemplate('another-module/my-controller/my-action');

return $view;
  }
}
```

You can see in the controller you are overriding the returned data with the form is a simple array and not even a view model. The redirect plugin returns a Response object.

So, you check whether the return value is an array and if so, you set the template explicitly. This skips the listener to inject the template name:

```
namespace MyAdminModule;

use ZfcUserAdmin\Controller\UserAdminController as BaseUserAdminController;

use Zend\View\Model\ViewModel;
use Zend\Http\Response;

class UserAdminController extends BaseUserAdminController
{
    public function createAction()
    {
        $result = parent::createAction();

if ($result instanceof Response) {
            // Old behaviour
            return $this->redirect()->toRoute('zfcadmin/zfcuseradmin/edit/:userId', 
                                              array('userId' => $user->getId()));
        }

// $result is array
        $view = new ViewModel;
        $view->setVariables($result);
        $view->setTemplate('zfc-user-admin/user-admin/create');

return $view;
    }
}
```

Because you set the template name directly now, you can skip your manipulation of the template map in your config. This also enhances flexibility because you hard-coded the template paths with paths outside your module. You also have the option now to override the zfcUserAdmin template map in another module.
